Kolts, J H

A process is described for preparing a composition or matter, which is useful and effective as catalyst composition for CO oxidation and consists essentially of (i) at least one metal oxide selected from the group consisting of alumina and magnesia, (ii) at least one noble metal selected from the group consisting of platinum and palladium and (iii) iron oxide, the process comprising the steps of (a) contacting a support material consisting essentially of at least one metal oxide selected from the group consisting of alumina and magnesia with a solution comprising at least one dissolved compounds of at least one noble metal selected from the group consisting of platinum and palladium and at least one dissolved iron compound, (b) heating the material obtained in step (a) under such conditions as to substantially dry the material obtained in step (a), to substantially convert at least one compound of at least one noble metal to at least one of oxides of Pt, oxides of Pd, Pt metal and Pd metal and to substantially convert at least one iron compound to iron oxide; and (c) heating the material obtained in step (b) in a reducing gas atmosphere at a temperature in the range of from about 550/sup 0/ to about 700/sup 0/C, under such conditions as to activate the material obtained in step (b) and to form the composition of matter.
